Part #: 399573

TCI stamped flexplates for Ford and Chevy applications are .035" thicker than stock, and the starter ring is welded to both sides of the flywheel for additional strength. Constructed from a high tensile strength material, these flexplates resist elongation and cracking. 168-Tooth flexplates have GM dual bolt patterns and are sized for stock 3/8" mounting bolts but can be easily drilled for 7/16" diameter high performance torque converter applications. Ford applications are balanced specifically for their appropriate engine/transmission combination.

This forged flexplate is for Pre-'86 SBC and all BBC engines. SFI 29.1 approved and internally balanced. 153 Tooth Count. Small Bolt Pattern.
